Abstract
A typical localizer capture and track mode of the automatic landing system control laws provided in new generation commercial airplanes is discussed. The linear control law consists of three separate modules: yaw damper, roll inner-loop, and localizer outer-loop. The yaw damper and roll inner-loop are used in conjunction with other modes of the roll axis control laws of the autopilot and are, therefore, predetermined for the localizer mode. The design includes feedforward, command shaping, and analytic gain schedules.<>
